Air conditioner system and air conditioner control method

Abstract

The invention discloses an air-conditioning system which comprises a compressor, a first outdoor heat exchanger, an indoor heat exchanger, a throttling assembly, a four-way valve, a cold storage device and a three-way valve. The cold storage device comprises a cold storage box containing a cold storage agent, a second outdoor heat exchanger and a third outdoor heat exchanger, wherein the second outdoor heat exchanger and the third outdoor heat exchanger are contained in the cold storage box; the first end of the three-way valve is connected with the four-way valve through the third outdoor heat exchanger, the second end of the three-way valve is connected with the four-way valve, and the third end of the three-way valve is connected with an exhaust opening of the compressor; and the second outdoor heat exchanger is connected between the throttling assembly and the indoor heat exchanger. The invention further provides a control method of an air-conditioner. According to the air-conditioning system and the control method, when the first end and the third end of the three-way valve are communicated, a refrigerant exhausted from the exhausting opening of the compressor absorbs the cold amount of the cold storage agent when passing through the third outdoor heat exchanger for reducing the temperature of the refrigerant passing through the third outdoor heat exchanger, the temperature of the refrigerant is reduced after the refrigerant passes through the indoor heat exchanger, the air return temperature of the compressor is reduced, the exhaust temperature of the compressor is further reduced, and normal running of the system is guaranteed.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioning system and a control method for the air conditioner. Background technique [0002] High-temperature areas have a large demand for refrigeration, but in the case of high ambient temperature, the refrigerant is difficult to condense, resulting in an increase in system pressure, an increase in compressor load, and an increase in exhaust temperature, which threatens the safety and reliability of the entire system and affects the reliability of the system. normal operation. Contents of the invention [0003] The main purpose of the present invention is to provide an air conditioning system and a control method for the air conditioner, aiming at ensuring the normal operation of the system during high temperature cooling. [0004] The present invention provides an air conditioning system, which includes a compressor, a first outdoor heat exchanger, an indoor heat e...
